A few months back, I bought 3 Astro Wars + sound pcb from a german guy, unfortunately I don't have a dedicated cab (yet), so I had to find another way to test them.
The pcb looks identical to Quasar, but I was not sure about the pinouts, I had to ask a Zaccaria expert in the States, to make sure, if I can test them in a Quasar cab.
Thanks for Digimon (Jörg), we had the manual for both boards and Paul was so kind to compare the pinouts and sent me this, as I'm not an expert in reading schematics (yet).
Seems like the 8 pin CN1 (power lines up) were ok and on the video side 7 PIN CN6 it looks like SYNC, GND and GREEN line up but the colours RED and BLUE are swapped, but it was not matter for testing.Ok, let's remove the Quasar board and plug in just CN1 and CN6
Hmmm., the pic was blue with some bars.
I had a feeling that it is not a pcb related problem, so I used the good old russian treatment, I hit the monitor frame a few times with a screwdiver and voila
You can see it in the top, that red and blue swapped, otherwise it works fine.
Pcb No.2. also works, but there is a horizontal line in the middle.
Pcb No.3. looks like broken, for first test, there was just garbage on screen
After a bit of reseating
It is better but still garbage.
I made a visual investigation on the pcbs and realized, that the processors? are not the same on the broken pcb.
Swapped both between them, but still the same dissorted pic.
That is where we are atm., looks like we have a fully working, an almost perfect and a broken Astro Wars pcb here.
